The following piece from Jim Meadows at Manual Therapy Online made me think.  It certainly presents findings most of us wouldn't have predicted.  Anyone else seen this work and and want to comment on the findings?
 
"  Last November, I was fortunate enough to attend the 2nd Annual American Academy of

    Orthopedic Manual Physical Therapy (AAOMPT) Conference in Biloxi MS. Among the

    many fine presentations I heard, Lance Twomey's ranks among the best. A highlight of his

    presentation was a summary he gave of a student's doctoral thesis on the independent

    benifit of a cervical collar for recent whiplash patients. The student's name was

    Gurumoorthy and his thesis earned him a Ph.D. and will be published soon in Spine.

    However, the information is so useful and for most therapists so radical that I thought that

    it would be appropriate to summarise Dr. Twomey's summary. I apologise in advance for

    any errors that I may make, they are inadvertent and caused by galloping senility.

 

    220 post whiplash victims were randomly divided into three groups the first being asked

    to wear a Philadelphia cervical collar for one month and then to discard it. These subjects

    were then put into group two. Group two subjects were assigned an active program from

    day 1 which consisted on non-painful range of motion and other painfree exercises. Group

    3 were left to the care of their physician (almost invariably a general practitioner) who

    usually prescribed analgesics, a soft collar and some form of self activation. The accident

    had to be within forty eight hours of attendence for the patient to be included as a subject.

    The subjects were tested by blinded assessors for pain, range of motion, strength and

    function. Pain was evaluated on a visual analogue scale, isometric strength by

    dynamometer, range of motion by goniometry and funtion by return to work. The subjects

    were evaluated at 4,6, 12, 26 and 52 weeks.

 

    In every category, the collared subjects did better than those in the other two groups.

    Perhaps one the most clear cut findings was in return to function. 50% of the subjects in

    the collared group were back at full function by the 26th week assessment. This figure

    was not achieved in either of the other two groups.

 

    This is almost unequivocal evidence of the value of a collar in the early stages of

    post-whiplash. The most amazing thing about the study is that it should have had to be

    carried out in the first place except as a means of confirming an established and obvious

    practice. With even a little thought is is obvious that an acutely injured neck requires the

    same care as an acute knee injury. That is rest while the inflammation subsides. In the

    knee patient we would have no trouble understanding the need to have the patient

    non-weight bearing, using a compression bandage, applying ice and generally resting it.

    But in the whiplash patient, there seems to be a lack of common sense by many health

    care providers from all disciplines. The sports medicine model is often applied

    indiscriminately with no thought to the fact that it is not an athlete that we are treating nor

    is it a sport injury. In any event, an athlete with an acute knee would be rested until the

    effusion had subsided and if this did not occur in a timely fashion, considerable expense

    and time would be spent investigating the reason for delayed recovery. If we (the

    combined health care professions) can be this concered about what is essenially a

    self-inflicted injury, why cannot we be so with some poor soul hit in the rear sitting at a

    traffic light. "  Jim Meadows -Manual Therapy Online
